What role does the lithium battery protection board play?

With the increasing demand for electronic products, people's demand for lithium batteries is also growing. As a type of battery with large electrical storage capacity, lithium batteries are used in various electronic products. However, some unscrupulous merchants in the market have targeted this point by bringing a large number of counterfeit and inferior batteries to the market, making it difficult for consumers to buy genuine products.

These counterfeit and inferior lithium batteries have many serious quality problems, and there is a high possibility of overcharging and overdischarging, which can lead to explosions. There is also a possibility of internal circuit short circuits causing explosions. However, there is a product that can effectively prevent issues such as overcharging, overdischarging, and internal circuit short circuits in lithium batteries, and that is the lithium battery protection board.

The lithium battery we use is actually composed of several small internal lithium batteries connected in parallel. There are several plastic like plates separating them in the gaps of the internal lithium battery. These small plastic like plates are lithium battery protection plates. But in fact, the lithium battery protection board is not made of plastic. But it is composed of several non-conductive fiberboards wrapped with a layer of oil on the outside. We all know that oil is non-conductive, which is why lithium battery protection plates can isolate lithium batteries and prevent short circuits in the circuit.
